Mineral particles sprayed out of the spherical ore pulp distributor 6 firstly move upwards under the driving of ascending water flow in the lower sedimentation zone 2 water, the gravity of the fine particles is smaller than the resistance, the fine particles reach the upper sedimentation zone 1 and then overflow into the overflow collecting tank 3, and the coarse particles slowly sink in the lower sedimentation zone 2 water and are collected in the thickening zone 10 because the gravity is larger than the resistance.

When the size fraction of the material to be screened is narrow: firstly, closing the valves of the overflow collecting tank 3, the middle collecting tank 8 and the sand setting discharge port 11, opening the valve of the middle ore discharge port 7, communicating the water inlet pipe 15 with an external water pump through a soft water pipe, after the water pump is opened, water flows enter the annular water distribution pipe 13 through the water inlet pipe 15, after the annular water distribution pipe 13 is filled, the water flows start to continuously inject water into the dense area 10 through the connecting pipes 14 which are equidistantly distributed in the circumferential direction, because the water flows respectively inject water into the dense area 10 through the connecting pipes 14 which are equidistantly distributed in the circumferential direction, a stable water injection liquid level can be quickly formed in the dense area 10, the turbulent flow is reduced through the flow stabilizing plate 9 in the process of slowly rising the water injection liquid level, after the continuously rising water injection liquid level rises to the top of the middle ore discharge port 7, the stirred ore pulp is injected into the grading equipment from the upper end port of the charging well 5 through the external hydraulic pump, and the ore pulp moves downwards under the action of pressure and gravity to reach the spherical ore pulp distributor 6, because a plurality of aperture has been seted up to ball-type ore pulp distributor 6 first, the ore pulp can be through the aperture under the effect of pressure upwards the portion divergent blowout for the ore pulp is more dispersed, has avoided traditional grading equipment to rely on the perpendicular feed of straight tube to arouse the blowout ore pulp and the rivers that rise to form the turbulent phenomenon of rivers that the convection current strikes and cause, has strengthened subsiding the grading effect. Mineral particles sprayed out of the spherical ore pulp distributor 6 are in water in the lower-layer settling zone 2, the gravity of fine particles is smaller than the resistance, the fine particles move upwards under the driving of ascending water flow to reach the middle ore discharge port 7, then the fine particles enter the middle collecting tank 8 through the middle ore discharge port 7, and coarse particles slowly sink in water in the lower-layer settling zone 2 and are collected in the dense zone 10 because the gravity is larger than the resistance. After a period of settlement and classification, the valve of the middle collecting tank 8 is opened firstly, fine particles gathered in the middle collecting tank 8 flow out along the water outlet under the impact of continuously introduced water flow at the moment, after no fine sand exists in the middle collecting tank 8 (namely no obvious sand exists in the liquid discharged from the water outlet of the middle collecting tank 8), the valve of the sand setting ore discharge port 11 is opened, coarse particles gathered in the dense area 10 are discharged through the sand setting ore discharge port 11 under the action of downward movement impact of the upper water flow at the moment, after the coarse particles are completely discharged, the external water pump is closed, and water supply is stopped.
Classification rule: when spherical solid particles settle in a stationary medium flow, see fig. 7, they are subjected to three forces, namely gravity, buoyancy and resistance. Gravity and buoyancy are determined by the density of the particles, the diameter of the particles and the density of the medium, regardless of the velocity of movement of the particles; the latter force is called a medium resistance, which includes a frictional resistance (viscous resistance) caused by shear stress and a pressure difference resistance (shape resistance) caused by deformation. The media resistance is a function of reynolds number and object shape, and when reynolds number is small, the media viscosity plays a major role, and thus frictional resistance is dominant; when the Reynolds number is medium, both functions; when the reynolds number is large, the pressure difference resistance plays a major role.
Gravity force
Buoyancy force
Resistance R ═ RN+RS (3)
Resistance to pressure difference
Frictional resistance Rs＝3πμdv (5)
So that R is phi ρ d2v2 (6)
Where ρ issIs the density of the spherical solid particles, g is the acceleration of the spherical solid particles under the action of gravity, dsIs the diameter of the spherical solid particles, ρ is the density of the liquid medium, v is the settling velocity of the solid particles, μ the viscosity coefficient of the liquid medium,
is the drag coefficient of the drag experienced by spherical solid particles.
When the spherical particles are completely immersed in the medium, the weight of the spherical particles in the stationary medium is
The spherical particles fall under the action of gravity, the speed of the spherical particles is gradually increased, the medium resistance borne by the spheres is also increased, and finally, the three forces are balanced, namely
Derived from the foregoing, i.e.
I.e. acceleration of the spherical solid particles of a-g0-aR (10)
G in the above formula0The acceleration of gravity of spherical solid particles in a medium is only related to the density of the particles and the medium, and is not related to the size and the moving speed of the particles.
A in the above formulaRThe acceleration is proportional to the square of the velocity of the spherical solid particles, and is also related to the size of the particles, the drag coefficient, and the density of the particles and the medium.
From the above analysis of the settling process of spherical solid particles in a static medium, the acceleration of the spherical solid particles is equal to the difference between the vectors of the gravitational acceleration and the resistance acceleration. When the particles just begin to fall when being immersed in the medium, the movement speed of the spherical solid particles is zero, the resistance acceleration is zero, and the movement acceleration of the spherical solid particles reaches the maximum and is equal to the gravity acceleration of the spherical solid particles in the medium; under the action of acceleration, the speed of the spherical solid particles is increased from zero, when the speed of the spherical solid particles is gradually increased, the resistance acceleration is also increased, the acceleration of the spherical solid particles is reduced, the speed increment of the spherical solid particles is reduced, but the spherical solid particles still do accelerated motion at the moment, and the resistance acceleration is further increased; when the acceleration of the spherical solid particles is equal to the acceleration of the spherical solid particles in the medium, the external force acting on the spherical solid particles reaches balance instantaneously, so that the spherical solid particles descend at a constant speed, and the constant speed is the final free settling speed of the particles.
When the spherical solid particles reach the final free settling velocity, the external force is balanced, namely the resistance of the spherical solid particles is equal to the gravity of the spherical solid particles in the medium, and the acceleration of the spherical solid particles is zero, namely
G0＝R，g0-aπ＝a＝0 (12)
Through the above further analysis, it can be solved that:
the V + is the free settling final velocity of the spherical solid particles in the static medium.
The flow velocity of the vertical medium which rises at a constant speed is V when the medium flows vertically upwardsaThe settling velocity of the spherical solid particles is V, by gravityThe direction is positive, and the flow velocity of the ascending flow is opposite to the gravity direction, so it is negative, so the relative velocity between the spherical solid particles and the fluid is:
Vc＝V-(-Va)＝V+Va (15)
the relative speed direction between the spherical solid particles and the vertical medium flow which rises at a constant speed is downward, and the resistance is opposite to the relative speed direction, so that the resistance direction is upward, and the resistance is equal to the resistance;
the kinematic equation of the vertical medium flow of the spherical solid particles ascending at a uniform speed is as follows:
as can be derived from the foregoing, it is,
is the free settling terminal velocity of spherical solid particles in a static medium flow,
thus making
Then
Can be simplified into
VC＝V+VaAnd V isaThe magnitude is constant, so that
Namely, it is
Because of g0Is a non-zero constant, therefore, there are
Vc＝V0＝V+Va (20)
V+＝V0-Va (21)
Velocity V as described above+Namely the final free settling velocity of the spherical solid particles in the vertical medium flow which rises at a constant speed, and as can be seen from the expression, the final free settling velocity of the spherical solid particles in the static medium flow is equal to the difference between the final free settling velocity of the spherical solid particles in the vertical medium flow which rises at a constant speed and the flow velocity of the vertical medium flow which rises at a constant speed.
By further analysis, it can be seen that V0-VaThe positive and negative relations between the spherical solid particles and the medium flow can judge the moving direction of the spherical solid particles in the vertical medium flow ascending at a constant speed.
When V is0-VaWhen greater than 0, i.e. V+If the value is positive, the spherical solid particles sink;
when V is0-VaWhen < 0, i.e. V+If the value is negative, the spherical solid particles rise along with the ascending medium flow;
when V is0-VaWhen equal to 0, i.e. V+Zero, the spherical solid particles are suspended in the ascending medium flow.
